$url->path_segments()

[Sean M. Burke]

One of the timid woodland creatures that read my /Perl and LWP/ book came 
and asked me a question the other day.  It's an interesting question with a 
somewhat surprising answer, so I'll copy it here:

Sorry to bug you, but I have a quick question I cant find the answer to.

When using URI::URL (or normal URI) and breaking down a url to grab 
$url->path_segments(); is the first one that is returned always blank or 
is it just me? and if this is correct, why is it always blank? I find 
myself having to grab $blah[1] to get the first actual segment.
I've been wondering about this for ages.  But just now I thought of the 
answer (or at least an answer): relative URL objects!  They don't have to 
start with a slash, so their $blah[0] might have something in it.

  DB<3> x $x->canonical->as_string
0  'stuff/things'
  DB<4> x $x->path_segments
0  'stuff'
1  'things'
